NON-REFILLABLE BOTTLE.

PECIFIGATION forming part of Letters Patent No. 766,008, dated July 26, 1904.

Application filed October 27, 1903. Serial No. 173,783. (No model.)

To all whom it may concern:

Be it known that I, JOHN IVHITELAW, gentleman, a subject of the King of Great Britain, residing at Burke Road, Camberwell, in the State of Victoria,Australia, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention has been devised to provide a practically non-refillable bottle for the prevention of fraud.

The object is achieved by providing Winding passages in the neck of the bottle with a valve just below, as hereinafter set forth.

Referring to the accompanying drawing, the figure is a vertical section through the neck of a bottle fitted with my invention.

In accordance with the invention one or more hollow spirals or winding passages A are provided in the bottle-neck for the outward passage of the contents, while below said spirals and at or about the base of said neck is a valve consisting, preferably, of a thimble or bowl shaped valve B on a suitable seating C and retained loosely in position on a short finger D, extending downwardly toward the hollow of said thimble and preferably made integral with the hereinafter-mentioned plug E.

The moclus operand i is as follows: After the bottle is filled the valve is dropped onto its seat and a ground glass or ordinary glass plug E, with a cork packing F, is then jammed down into the neck, so as to be irremovable.

It will thus be seen that while the contents may be discharged freely any attempt to dilute or adulterate the contents or recharge the bottle is practically impossible, because when the bottle is upright the valve B checks the entrance, and if the bottle be turned upside down only a certain small quantity of liquid can be forced into the spirals, and the encaged air being unable to escape prevents the introduction of liquid, while when laid on its side an air-lock is formed in the winding passages.

W'hen discharging the contents, and especially when the bottle is full, it is necessary to give the bottle a slight jerk to displace the valve.

Having described my invention, what I claim is- 1. In a non-refillable bottle, the combination with the bottle provided with an integral neck, said neck being provided upon its interior with convoluted passages, of a glass plug provided with a cork jacket inserted in said neck, a seat formed in the bottom of the neck, and a hollow valve normally resting on said seat and centered about the lower end of said plug, substantially as described.

2. A non-refillable bottle provided With a convoluted outlet in the neck, an irremovable plug fitted in said neck, a finger on the lower end of the plug, a seat in the bottom of the neck, and a hollow valve normally resting on said seat, the finger on the end of the plug being centered in said valve, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN WHITELAIN.
